9-2-110 Exemptions: The limitations of this Rule shall not apply to concentrations of hydrogen sulfide occurring
on the property where the emissions occur providing that such property, from the emission point to the point of
any such concentrations, is controlled by the person responsible for the emission.

9-2-300 STANDARDS

9-2-301 Limitations on Hydrogen Sulfide: A person shall not emit during any 24 hour period, hydrogen
sulfide in such quantities as to result in ground level concentrations in excess of 0.06 ppm averaged over three
consecutive minutes or 0.03 ppm averaged over any 60 consecutive minutes.

9-2-500 MONITORING AND RECORDS

9-2-501 Area Monitoring Requirements: Any person emitting hydrogen sulfide from any source is subject
to the monitoring, maintenance, records and reporting requirements of Regulation 1, including Sections 1-510, 1-530,
1-540, 1-542, 1-543, and 1-544.

9-2-600 MANUAL OF PROCEDURES

9-2-601 Ground Level Monitoring: The monitoring requirements for ground level concentrations of hydrogen
sulfide, including siting procedures and instrument specifications, calibration and maintenance procedures, are
described in the Manual of Procedures, Volume VI, Section 1. (Amended March 17, 1982)
